BRICK-KILN.

SPECIFICATION forming part of Letters Patent No. 548,708, dated October 29, 1895.

Application filed February 23,1895. 561mm,. 539,4 2. (110 may To all whom it may concern:

Be it known that we, CHARLES L. HORN and WILLIAM M. IRWIN, citizens of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in BrickKilns, of which the following is a specification.

Our invention relates to that class of kilns known as continuous kilns, wherein the bricks to be burned are stacked in aoontinuous arched burning-chamber and the fire passes through them horizontally; and the objects of our invention are, first, to provide a continuous kiln wherein the water-smoke and products of combustion may be allowed to escape from the top or the bottom of the burning-chamber as the conditions may require; second, to provide a continuous kiln wherein the escaping heat of the cooling brick may be utilized better than heretofore in the drying of the green brick, or bricks recently placed in the kiln preparatory to burning; third, to equalize the heat in the burningchamber, so that all the bricks stacked therein may be burned to uniform color and equal hardness. We attain these objects by the method of construction illustrated in the accompanying drawings, in which- Figure 1 is a ground plan of one end of a kiln embodying our invention. Fig. 2 is a sectional plan of the same, taken on the dotted line 11 y of Fig. 3. Fig. 3 is 'a vertical section taken on the dotted line w m of Figs. 1 and 2. Fig. 4 is a top plan view. Fig. 5.is a broken verticalsection taken on the dotted line K K of Figs. 1 and 4. 1

Similar letters refer to similar parts th rough out the several views.

The burning-chamber A consists of two parallel arched passages separated throughout their entire length by a heavy central.

partition-wall and connected at their ends by semicircular arched passages of like sectional area, so as to form an endless arched passage in which the bricks are stacked to be burned. This burning-chamber A is divided into a number of sub-chambers or compartments by means of removable partitions attached to the interior projecting shoulders or pilasters a. Each compartment of the burning-chamber A communicates with the external air by meansof an arched doorway I, which doorway is closed by a brick wall while the burning process is going on in that compartment.

Constructed within the heavy central partition-wall hereinbefore mentioned and extending nearly the full length thereof is the longitudinal smoke-chamber B, which communicates throughan underground line with a suitable chimney located outside the kiln. Smoke-chamber B has in its top a number of draft-openin gs, which communicate by means of short vertical fiues H with horizontal transverse fiues D, referred to hereinafter.

O is the longitudinal air-chamber, also'constructed in the heavy central partition-wall and extending nearly the full length thereof. This air-chamber O is erected on the same horizontal plane as the smoke-chamber B and has in its top draft-openings similar to and in alignment with the draft-openings in the top of the smoke-chamber B aforesaid and with draft-openings in the top of the burningchamberA. Draft-openings in the top of the air-chamber C communicate by means of short vertical fiues F with transverse horizontal fiues D. Horizontal transverse fiues D extend across the top of each compartment of the burning-chamberA and across the tops of the smoke-chamber B and of the air-chamber 0. Short vertical fiues H connect the fiues D with the draft openings in the top of the smoke-chamber E. Short vertical fiues F like wise connect the fiues D with the draft-openings in the top of the air-chamber O.

In the walls on both sides of each compartment of the burning-chamber A, nearthe end of the compartment and at the bottom thereof, are, placed draft-openings E.

By means of the short vertical fiues Geach one of the flues D is connected with the draftopening in the top of the compartment of the burning-chamber immediately beneath it, and by means of the inclined fiues 6,. Fig. 5, each one of the fiues D is connected with the draftv IOO E, F, and H", respectively which rods extend upward through the covering of fines D and through the top of the kiln. The dampers G are manipulated with a rod introduced after removing the removable cover G" in the top of the fines D.

Suitable holes or openings J extend from the top of the kiln to theinterior of the burning-chamber A to serve for the introduction of fuel. Said holes or openings are closed by suitable removable covers J. Pockets K in the walls of the kiln are filled with sand, clay, or other suitable material.

In the operation of the kiln, if the dampers e and H be opened over those compartments through which the products of combustion are circulating, these products of combustion with the accompanying moisture or watersmoke will pass from the bottom of the burning-chamber A through openings E, fines e and D into the smoke-chamber B, and thence to the chimney. If, instead, the dampers G and H be opened, the products of combustion and the Water-smoke will pass from the top of the burning-chamber A to the chimney, as aforesaid.

If at the point where the bricks are burned and cooling down the dampers G and F be opened and at that point where the green bricks have been recently stacked in the kiln the dampers G and F be opened, the heated air from the cooling bricks will pass through fines G, D, and E" into hot-air chamber '0, through hot-air chamber 0 to the point oppo-v site the green brick, and thence through fines F, D, and G, circulating through the green brick, drying the same thoroughly before they are exposed to the greater'heat of the escaping products of combustion. The resnltant water-vapor is allowed to escape by opening the dampers e and H over the next adjoining compartment.

We are aware that prior to our invention continuous kilns have been constructed having hot-air chambers, central smoke-chambers, vertical fines, and horizontal transverse fines. We therefore do not claim such a combination broadly; but

What we do claim as our invention, and desire to secure by Letters Patent, is

The combination, in a continuous kiln, with a centrally located longitudinal smoke chamber having in its top a series of draft openings, a centrally located longitudinal hot air chamber having in its top a series of draft openings similar to the draft openings in the top of the smoke chamber, and horizontal transverse fines extending over the tops of the burning chamber, smoke chamber, and hot air chamber, of vertical fines connecting the horizontal transverse fines and the draft openings in the top of the burning chamber, vertical fines connecting the horizontal transverse fiues and the draft openings in the top of the smoke chamber, vertical fines connecting the horizontal transverse fines and the draft openings in the top of the hot air chamber, and inclined fines connecting the horizontal transverse flnes'and the draft openings at the bottom of the burning chamber, all substantially as herein described.

In testimony whereof We have hereunto affizred our signatures in the presence of two witnesses.
